Hello all. I am making a group project to optimize flap deflaction in flight on airplanes. We are using the Arduino nano and two Sensors. One of the sensors is the MPXV7002DP for the airspeed. now i want to know how this sensor should be written in the Arduino IDE? We want to get the speed. Is the MPXV7002DP only a pressure sensor and we have to use something with the voltage or is it in meter per second.
This is the code i have written so far:
const int FIRST_THRESHOLD = 0.267;
const int SECOND_THRESHOLD = 0.426;
const int THIRD_THRESHOLD = 0.764;
const int FOURTH_THRESHOLD = 0.952;
const int M = 350;
const int P = 1.124;
const double A = 10.5;
const double G = 9.81;
//init pins
int speedSensor = A1;
int accelerationSensor = A4;
//LED pins
int firstLed = 2;
int secondLed = 3;
int thirdLed = 4;
int fourthLed = 5;
int fifthLed = 6;
int WAIT = 500;
double determineLiftCoefficient(int speedValue, int accelerationValue){
double result = 0.0;
result = (2 * M * G * accelerationValue) / (P * speedValue * speedValue * A);
}
void setup() {
// put your setup code here, to run once:
pinMode(speedSensor, INPUT);
pinMode(accelerationSensor, INPUT);
pinMode(firstLed, OUTPUT);
pinMode(secondLed, OUTPUT);
pinMode(thirdLed, OUTPUT);
pinMode(fourthLed, OUTPUT);
pinMode(fifthLed, OUTPUT);
}
void loop() {
// put your main code here, to run repeatedly:
int speedValue = analogRead(speedSensor);
int accelerationValue = analogRead(accelerationSensor);
double liftCoefficient = determineLiftCoefficient(speedValue, accelerationValue);
//Serial.println(speedSensor);
if(liftCoefficient < FIRST_THRESHOLD){
digitalWrite(firstLed, HIGH);
}
else if(liftCoefficient < SECOND_THRESHOLD){
digitalWrite(secondLed, HIGH);
}
else if(liftCoefficient < THIRD_THRESHOLD){
digitalWrite(thirdLed, HIGH);
}
else if(liftCoefficient < FOURTH_THRESHOLD){
digitalWrite(fourthLed, HIGH);
}
else{
digitalWrite(fifthLed, HIGH);
}
delay(WAIT);
}
